Can you explain how you would do this? Would you press the button while the motor is running? Wouldn't this either put an excessive load on the pack and or confuse the meter? I'm very slow when it comes to electronics so please pardon the question.
No problem as the pulse is so short; I have plotted the ESR of a lipo pack being discharged at constant current at max C rating and plotted the ESR of the pack by taking readings every 10 seconds. You don't need to remove the steady load, just connect the meter in parallel, as close to the pack as possible to avoid extra connector and lead losses.
